不胜感激！

Our library only includes this journal from 2004 onwards, sorry i can't help you. However there is a slight mistake in the information you provide. The correct one is as follows:
Reiner, E. & Rubinstein, M., "Breaking Down the Barriers", Risk 4, 8, pp. 28-35 (Sep 1991)

請收下.

I am so gald to download the PDF from you,thank you very much! I look for it for a long time .Another article aslo writen by Rubinstein named "Unscrambling the Binary Code" in Risk Management is very good for studying barrier options.Thank you again!
